APPLIES TO:
Oracle Database - Enterprise Edition - Version 11.2.0.1 and later
Information in this document applies to any platform.
GOAL
Consider a 11.2 Grid Infrastructure with CLUSTER setup having OCR ,Vote File and ASM SPFILE on a diskgroup. Under certain circumstances you may wish to rename that diskgroup.
"renamedg" utility can be used to rename of the diskgroup when the diskgroup is dismounted.
But since the diskgroup contains OCR and Vote File we need to use an intermediate diskgroup for storing OCR and Vote File temporarily while renaming the actual diskgroup.
SOLUTION
Basic Steps to rename the diskgroup :
\1) Create a temporary diskgroup (TEMP) with suitable redundancy for OCR and Vote files.
\2) Move OCR and Vote file from
\3) Change ASM SPFILE location from
\4) Restart CRS in all Nodes to Startup CRS using New SPFILE from
\5) Dismount the OLD diskgroup in all cluster nodes that is not used by CRS.
\6) Rename OLD diskgroup to NEW diskgroup
\7) Mount the renamed diskgroup .
\8) Move OCR and Vote file from TEMP diskgroup to renamed diskgroup.
\9) Change ASM SPFILE location from
\10) Restart CRS in all nodes to startup CRS using new SPFILE from renamed diskgroup.
NOTE: Modify the asm resource to have the correct password file location else startup CRS will not start the ASM resource
\11) Drop the intermediate diskgroup TEMP.
\12) Need to remove the diskgroup resources TEMP and
\13) Ensure ALL cluster resources are started successfully .
Below assumptions are made :
-> Name of Temporary diskgroup is TEMP.
-> OCR,Voting Disks and ASM SPFILE are originally stored in a diskgroup DATA.
-> Diskgroup DATA should be renamed to CRS.
-> $ORACLE_HOME points to GRID Home.
-> Cluster is up and running in all nodes of RAC.
Detailed steps with commands to rename the diskgroup :
\1) Create a temporary diskgroup :
Login as SYSASM using SQLPLUS into ASM instance on one node and run below commands:
create diskgroup TEMP normal redundancy disk
attribute 'compatible.rdbms'='11.2.0.0', 'compatible.asm'='11.2.0.0', 'au_size'=
